How long does invoice-to-payment actually take?

Measure completed invoice-to-payment intervals, or use a quick monthly estimate when individual receipt dates are not available.

Calculation mode

Detailed mode measures completed invoice-to-payment intervals. Entries without a payment date stay excluded; the calculator never invents one.

Conceptual timing strip. This public calculator measures invoice date to payment date; it is not the in-product deal-to-first-receipt metric.

5 incomplete entries are excluded. An unpaid invoice remains unpaid; no payment date is assumed.

Results summarize the completed dates and amounts entered. They do not predict when an unpaid or future invoice will be received.

This public calculator uses invoice date to payment date. Detailed mode summarizes completed observations; an invoice without a payment date stays excluded rather than receiving an invented date.

Quick mode applies a typical days-to-payment assumption to typical monthly invoicing. The result is a planning estimate of receivables exposure, not a prediction of when a particular payment will arrive.

RunwayCal's in-product Collection Speed has a different verified boundary: deal or expected-cash context to first landed receipt. Collections Planning keeps expected and received cash separate when that timing enters the wider plan.
